Description
The IL41050 is a galvanically isolated, high-speed CAN (Controller
Area Network) transceiver, designed as the interface between the
CAN protocol controller and the physical bus. The IL41050 provides
isolated differential transmit capability to the bus and isolated
differential receive capability to the CAN controller via NVE’s
patented* IsoLoop spintronic Giant Magnetoresistance (GMR)
technology.
Advanced features facilitate reliable bus operation. Unpowered nodes
do not disturb the bus, and a unique non-volatile programmable
power-up feature prevents unstable nodes. The devices also have a
hardware-selectable silent mode that disables the transmitter.
Designed for harsh CAN and DeviceNet environments, IL41050T
transceivers have transmit data dominant time-out, bus pin transient
protection, thermal shutdown protection, and short-circuit protection,
Unique edge-triggered inputs improve noise performance. Unlike
optocouplers or other isolation technologies, IsoLoop isolators have
indefinite life at high voltage.
Single-chip isolated CAN/DeviceNet transceiver
Fully compliant with the ISO 11898 CAN standard
Best-in-class loop delay (180 ns)
3.0 V to 5.5 V input power supplies
>110-node fan-out
High speed (up to 1 Mbps)
2,500 V
Very low Electromagnetic Emission (EME)
Differential signaling for excellent Electromagnetic Immunity (EMI)
30 kV/µs transient immunity
Silent mode to disable transmitter
Unpowered nodes do not disturb the bus
Transmit data (TxD) dominant time-out function
Edge triggered, non-volatile input improves noise performance
Bus pin transient protection for automotive environment
Thermal shutdown protection
Short-circuit protection for ground and bus power
−55°C to +125°C operating temperature
0.15" and 0.3" and 16-pin JEDEC-standard SOIC packages

... TxD. If the duration of the low is longer than the internal timer value, the transmitter is disabled, driving the bus to the recessive state. The timer is reset by a positive edge on pin TxD. If power is lost on Vdd2, the IL41050 asserts the RxD output high when the supply voltage falls below 3.8 V. RxD will return to normal operation as soon as Vdd2 rises above approximately 4.2 V. ...
